Re: Suitable mechanism for Theorems and Definitions

[Taco Hoekwater <taco@elvenkind.com>]

Hi David,

Not sure if you are still interested, but here is my "optional title"
hack, revamped for a modern context distro. It creates a second
extra optional argument for the enumeration, nothing too fancy.
The example also shows a way in which you can access the number.

This does not solve the list generation, sorry.

Cheers, Taco
